自然铜矿石样品的加工及分析测试方法

Processing and Analysis of Native Copper Ore Samples

摘要: 对滇东北地区典型自然铜矿石样品的试验采取、粒度分级过筛、缩分及均匀性试验,认为样品在经过粗碎、中碎后,将颗粒大于2 mm的矿物(95%以上为自然铜)用2 mm隔筛分离后,余下样品经过棒磨,过0.246 mm(60目)筛后进行缩分至常量细碎样品量,再进行0.074 mm(200目)样品加工的工艺流程是可行的.样品中铜元素分析方法(原子吸收光谱法、碘量法和碘氟法)的选择符合矿区实际,其经济性、可靠性、准确性能满足地质工作的实际需要.

Abstract: Through the experiments of sampling, sizegrading, screening, splitting and homogeneity test for the native copper ore samples from northeast Yunnan province, a sample processing procedure was established. After rough and medium crushing and screening out the grains with grain size 2 mm screen (>95% is native copper), the sample was rod grinded, passing through 0.246 mm（60 mesh） screen, splitting and prepared to 0.074 mm（200 mesh）. Atomic absorption spectrometry, iodimetry and iodinefluorine methods were selected for copper analysis with good accuracy, reliability and economical efficiency.
